Professional Disc for Data
The Professional Disc for Data ( PDD ) is a variant of the Blu-ray Disc (BD) from the manufacturer Sony , which was specially created for professional storage solutions in companies. The PDD was unable to prevail over the UDO , and further development and sales were discontinued in 2006; support for the devices ended in 2014.

The capacity of the single-sided writable data carrier should be over 23 GB and is thus several times higher than that of a conventional CD (capacity around 700 MB ) or DVD (capacity 4.37 or 8.5 GB ). The procedure for data storage uses the phase change technique , in which a blue laser is used, as with the PDD. The sensitive, only 0.1 mm thin data carrier protection layer of the discs is protected by an airtight caddy .
history
The first versions of the associated optical drives came onto the market in Japan in May 2004 .
The PDD should be available both as a WORM medium (Write Once Read Multiple times) and as a rewritable RW medium.
The PDD is based on the DVD successor Blu-ray Disc and competes with the Ultra Density Optical (UDO). Due to incompatibilities with existing backup solutions based on MOD , which is popular in the corporate sector , PDD was unable to gain acceptance due to the high conversion costs.
Sony stopped developing the PDD in early 2006 .
